Thanks to the new image signal processor (ISP) in the Apple A7, the iPhone 5s iSight camera also gets better balance, better exposure, better sharpness, better low-light, less color distortion, less motion blur. It's still 8 megapixels but it's got a wider f/2.2 aperture and bigger 1.5 micron sensor. The rear-facing iSight has also been improved for the iPhone 5s.
If your phone is rebooted or if you haven't used Touch ID for 48 hours, you'll have to use your passcode to reactivate it. Each Touch ID sensor is paired with a specific Apple A7 processor, and the fingerprints are never allowed out of the Touch ID system and never transmitted or stored on any servers. It works with a capacitive sensor that detects your finger, snaps a high-resolution image of it, converts it to a mathematical hash, sends it directly to a secure enclave on the Apple A7 chipset and, if it matches, releases a yes/no token that either verifies or rejects your print. It lets you use biometric authentication to unlock your iPhone and authorize purchases on the iTunes Store, App Store, and iBookstore. Touch ID, Apple's fingerprint identity sensor, debuted with the iPhone 5s. iPhone 5s: Touch ID fingerprint identity sensor in the background in a really power-efficent way and then shares it with iOS and apps so not only can your phone make sure your pedometer apps don't have any gaps, but can recognize when you're not moving and power down network connections to save even more power, or recognize when you get out of a car and switch you to walking directions. The M7 collects all motion-related data - accelerometer, gyroscope, magnometer, etc. The Apple A7 architecture also includes Apple's first coprocessor, the Apple M7. That means the iPhone 5s is not only one of the most advanced mobile devices on the planet but that it can run more complex apps and games faster and better than ever before. The A7 includes a 1.3GHz dual-core custom Cyclone processor based on the ARM v8 instruction set, and a OpenGL ES 3.0-equipped PowerVR G6430 graphics processor.
It's the first 64-bit SoC on the market and that Apple got there before companies that fabricate their own chips is a testament to Apple's drive. The iPhone 5s is powered by the 64-bit Apple A7 system-on-a-chip (SoC). Also, like every s-branded phone Apple has released to date, beneath a similar-looking shell beats the heart of a much-improved beast. The iPhone 5s not only comes in dark and light colors, space gray and silver respectively, but it comes in gold.
With this phone, however, there's one notable exception. But that's been true for every s-branded phone Apple has released to date. Physically the iPhone 5s looked identical to the previous year's iPhone 5, including the 4-inch 1136圆40 in-cell display. The 5s was introduced by Phil Schiller at the iPhone event on Septemand released on September 20 alongside iOS 7. The iPhone 5s is Apple's 7th generation iPhone.
